Femoral artery puncture positioning technology of mark point assisted mixed reality technology

Abstract

The invention relates to a femoral artery puncture positioning technology of a mark point assisted mixed reality technology. The femoral artery puncture positioning technology includes the steps: (1)placing at least three markers made of imitation bone materials at the thigh of a human body, forming a plane by the markers and marking the placement positions of the markers by coloring; (2) generating two-dimensional images by CT (computerized tomography) scanning; (3) performing a three-dimensional reconstruction technique on the two-dimensional images to obtain a 3D (three-dimensional) model;(4) accurately matching the 3D model with the colored markers on the human body by a mixed reality device; (5) confirming the position, the angle and the depth of a puncture needle; (6) positioning the position of a femoral artery by dyeing after needle insertion. The position of the femoral artery is accurately positioned by the mixed reality technology without repeated scanning and repeated puncture, the shortcoming of blind puncture is thoroughly overcome, the pain of a patient is greatly relieved, and surgical efficiency is improved.

Description

technical field [0001] The invention belongs to the field of image recognition and medical image processing, and relates to a femoral artery puncture positioning technology based on a marker-assisted mixed reality technology. Background technique [0002] Interventional therapy uses medical imaging equipment such as X-ray fluoroscopy, CT positioning, and B-mode ultrasound as a guide, and inserts a special catheter or device into the human body through human arteries and veins. The most commonly used is the femoral artery. The femoral artery originates from the external iliac artery and is close to the inguinal ligament at the base of the thigh. The femoral pulse can be palpated at the femoral triangle inguinal ligament. Make a line from the pubic symphysis to the external anterior superior iliac spine, and the femoral artery passes through the midpoint of this line, at the inguinal ligament. The femoral artery runs almost parallel to the spine at the groin. At present, the...
